Specification of Letters Patent.

Patented June 16, 1914.

Application filed July 20, 1912. Serial No. 710,690.

To all whom it may concern Be it known that I, BOULTBEE BROOKS, subject of the King of Great Britain, residing at Criterion Wbrks, Great Charles street, Birmingham, England, have invented certain new and useful Improvements in Motor-Cycle, Cycle, and analogous Saddles or Seats, of which the following is a speciiication.

rIhis invention relates to motor-cycle, cycle, and analogous .saddles and seats of that type in which the seat proper is controlled inV its movement in relation to the base trame, and is constrained to move bodily in a vertical direction, by a system of parallel-motion links jointed at one end to the said base frame and at their other ends to hangers depending from the seat frame, or certain of them jointed to hangers and others to the seat frame.

The object of the present invention is to bring the spring system immediately under its load so as to obtain the greatest possible advantage from the springs, and consequently greater comfort and resiliency, all vibration and shock due to inequalities in the road being e'nqcctively absorbed or neutralized.

The invention consists essentially in directly supporting the seat solely upon verticallydisposed coiled springs which are connected with the base frame and are situated immediately or approximately beneath the center of gravity ot the load so that the weight is borne directly by the said springs; the vertical movements of the seat being controlled by the parallel motion links, and the seat frame hangers to which the said links are attached preferably (though not necessarily) being situated in the same transverse plane as the aXes of the springs so as to also come directly under the load.

Figure l of the accompanying drawings represents a part sectional elevation of a motor-cycle saddle constructed in accordance with the present invention. Fig. 2 is an end view showing the springs in section. Fig. 3 illustrates, in sectional elevation, another modified form of saddle. Fig. 4 is an end view, but showing the springs in section. Figs. 5 and 6 illustrate two further modifications.

Referring to Figs. 1 and 2, the seat frame comprises a shaped metal plate a provided at each side, at some distance forward of the rear end, with a depending hanger or bracket CZ, arranged directly under the load (for the normal position of the rider). To give the Vertical rising and falling action to the seat a pair of superposed parallel motion links e, el, is employed at each side ot' the saddle. At one of their ends they are jointed to a rigid base bracket or frame f, While their rear ends are jointed to the hangers ai. To resiliently support the seat g these hangers d are prolonged below the links to form thrust rods and are attached to the upper ends of the inner coiled compression springs L of a compound tension and compression system, the lower end of the inner spring being attached to the lower coil ot' an outer concentric extension spring /tl which is suspended by its upper end from the rear eX- tremity of the base frame f. The latter consists of a pair of sheet steel side plates tied Atogether by the boss or attachment clip y'.

No special provision is made for supporting the peak of the saddle, the whole seat being supported through the medium of the springs la, itl, attached to the hangers. lIhus, when the load comes upon the saddle, the springs directly receive the downward thrust, and the seat is constrained to move bodily in an approximately true vertical direction by reason of the controlling links e, elf Instead of the springs being of the compound type they may consist of simple eX- tension springs.

In the modifications represented in Figs. 3 and 4, instead of both the parallel motion links at each side being situated above the springs, the one, el, is arranged above, and is jointed to the hanger d, and the other, e, is arranged below the springs, each link e being jointedly attached at one end to the lower end of the corresponding hanger d (which passes through the inner spring h) and at its other end to the adjacent end of a horizontal cross rod Z5 mounted in the lower end of a depending part f1 of the base bracket f. The outer springs itl are attached at their upper ends to the said bracket j", and at their lower ends to the inner springs h. Each hanger d has a collar Z1 that bears on the top of the adjacent spring t. The seat :trame a is shown as consisting of wire rodding.

In the arrangement shown in Fig. 5, the hangers d to which the links e, el, are attached, are jointedly connected at Z4 to the seat stretcher or frame members a, and a pair of horizontal buler or cushioning springs m or other resilient devices are provided between the opposite sides of depending part al of the said frame members and suitable abutments Z2 upon laterally extending arms cl3 of the hanger members CZ. Then so long as the rider is seated in the correct position the thrust is direct, but if he sit too far forward or too far to the rea-r, one or other of the springs m or other resilient devices will yield and relieve the parts of undue strain.

As an alternative, the construction shown in Fig. 6 may be employed, in which the resilient devices fm, are interposed vertically between the underside of the seat frame a and the upper edges of the lateral arms cl3 of the jointed hangers d.

The load-supporting springs h1 in Figs. 5 and 6 correspond to the springs h1 in Figs. 1 and 2 and have a similar mounting and arrangement.

Having fully described my invention,

what I desire to claim and secure by Letters Patent is In motor-cycle, cycle and analogous saddles and seats, the combination, with the seat proper, and depending members connected thereto, of a base frame, parallel-motion links connected with said frame for constraining said seat to maintain a constant inclination during its rising and falling movements, and vertically-disposed coiled springs connected with said depending members and said base frame and located directly under the load, said springs constituting the sole support for said seat.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

BOULTBEE BROOKS.
